' ers.

The object ofmy invention is to provide means adapted to cooperate with mechanism of the character mentioncd' whereby the note sheet will be automatically caused to follow a comparatively direct course over the tracker-bar of an lnstrument of a nature a stated so as to effect the correct rendition of the music;

A further object is to provide a mechanism of such character which willbe effectual initsoperation, and strong, durable and comparatively simple of construction.

Other objects will appear hereinafter.

With these objects in view my invention consists in a mechanism characterized as above mentioned and in certain deta ls ofconstruction and arrangement of parts all as willbe hereinafter fully described and particularlypointed out in the claims. v

M invention will be more readily understood by reference to: the accompanying drawings forming apart of this specification, and in which, 7 V

projecting from the upper extremities of the brackets 1 1 is a forked frame 3 in the upwardly extending arms 4; .of which are JOLII'HalBd the spindles of the usual removable roller 5 upon which is carried or coiled the note sheet to 'befed over the instrument 1- 1, the

A bar 9fixed'as at 10 and 11 to the frame 3 and at 12 to the extremity of the spindle 13 of the roller 8 effects the simultaneous movement of said frame and roller.

the lower portion of 14 indicates the usual tracker-bar or'duet bridge spanning the brackets 11 at a point intermediate the rollers 5- and 8, the same being secured to the brackets 1-1 by screws 1 5 passing through slots 16 provided in either of the extremities of said bar, said into bosses 17 formed screws being threaded upon the inner surfaces of the brackets 1-l. Arranged upon the inner surfaces of the upon screws 18 the heads of which'are rotatably. mounted in said brackets, hence permitting of inde endent lateral adjustment thereof, are pref erably rectangular blocks '19.
